The device oi .myjpresent invention is constructed along lines somewhat 'similar to tlfiose illustrated in an application "Serial No.,397,02 1, filed by Loy D. Hagenbookon June 7,"l94 l,'but difiers therefrom in that anfirnprovedform of connecting means' is provided betweenj'the' ahcho'rin'g device and thedrive mechanism, which facilitates the" liningup and the connecting oi the drive mechanism with the anchoring device. 5 1 Other objectsofmy-inventionwill appear from time-to time as the fol-lowingspecification proceeds and with reference drawings wherein: I -v -Figure 1' is a plan view of a shaker 'conveyer tothe accompanyingj Said 7 driving links arefconnected between the rocking flarrns l2; l2 and opposite ends of a con ncting bar' 16; which is securedto the 'botto'rnf of, said trough section and extends laterally -fror'n opposite sides thereof.
